| Résumé | Recently a time difference measurement system was developed in the Frequency & Time Standards Section of the National Bureau of Standards and independently at the National Research Council which shows more than three orders of magnitude improvement over that which is currently available commercially. Current state-of-the-art time difference measurement devices have specified accuracies of about 1 nanosecond. Measurement precision and potential accuracy of better than 1 pico-second has been demonstrated in this new time difference measuring device. This has significant implications in frequency and time metrology using: state-of-the-art frequency standards and clocks. A brief report was given on this measurement system at the PTTI Planning Meeting at the Naval Research Laboratory on the 5th of December 1974. This paper will give more detailed circuit diagrams necessary to build up such a measurement system.
This particular measurement system has the advantage that it can measure time differences with accuracies of a few picoseconds and with repetition rates ranging from a few milliseconds to as slow a repetition rate as would be desirable, thus expanding convenient measurement of time domain stabilities of frequency and time standards over several decades with only one measurement system. The system is also very amenable to self-calibration and self-noise analysis. Specifically, a fractional frequency stability of about 10¹⁶ was measured for the noise of this measurement system at a sample time of 10³ S. |
